无限轮播

写一个线程:

       

Handler handler =new Handler(){
    @Override
    public void handleMessage(Message msg) {
        super.handleMessage(msg);
        int currentItem = pager.getCurrentItem();
        pager.setCurrentItem(currentItem+1);
        handler.sendEmptyMessageDelayed(0,2000);
    }
};

加点操作:

  

public void jiadian() {
     ll = (LinearLayout) findViewById(R.id.ll);//得到LinearLayout布局

        image.clear();清空图片集合
         ll.removeAllViews();//清空LinearLayout布局
    for (int i=0;i<list.size();i++)//添加
        {
             imageView = new ImageView(MainActivity.this);//创建一个图片布局
             if(i==0)
             {
                 imageView.setImageResource(R.drawable.dot_focuable);
             }else
             {
                 imageView.setImageResource(R.drawable.dot_normal);
             }
            LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(20, 20);//圆点大小
            if(i==0)
            {
                layoutParams.setMargins(250,0,20,0);//间距
            }else
            {
                layoutParams.setMargins(20,0,20,0);
            }
            image.add(imageView);//圆点添加到图片集合中
            ll.addView(imageView,layoutParams);//圆点添加到LinearLayout中
        }
}

监听:

  

pager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

    }

    @Override
    public void onPageSelected(int position) {

        for (int i=0;i<list.size();i++)
        {
            if(i==position%list.size())
            {
                      image.get(i).setImageResource(R.drawable.dot_focuable);//修改图片颜色
            }else
            {
                image.get(i).setImageResource(R.drawable.dot_normal);
            }
        }
    }

    @Override
    public void onPageScrollStateChanged(int state) {

    }
});


class Mypager extends PagerAdapter{

    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        ImageView imageView = new ImageView(MainActivity.this);
        imageView.setScaleType(ImageView.ScaleType.FIT_XY);
        ImageLoader.getInstance().displayImage(list.get(position%list.size()),imageView);
         container.addView(imageView);
         //图片点击监听
       imageView.setOnTouchListener(new NewTouchListener());
      return imageView;    }    @Override    public void destroyItem(ViewGroup container, int position, Object object) {        container.removeView((View) object);    }    @Override    public int getCount() {        return Integer.MAX_VALUE;    }    @Override    public boolean isViewFromObject(View view, Object object) {        return view==object;    }}
当点击图片时候让图片停止
private class NewTouchListener implements View.OnTouchListener {

    @Override
    public boolean onTouch(View arg0, MotionEvent arg1) {
        // TODO Auto-generated method stub
        switch (arg1.getAction()) {
            case MotionEvent.ACTION_DOWN:
                handler.removeCallbacksAndMessages(null);
                break;
            case MotionEvent.ACTION_CANCEL:
                handler.sendEmptyMessageDelayed(0, 2000);
                break;
            case MotionEvent.ACTION_UP:
                handler.sendEmptyMessageDelayed(0, 2000);
                break;
            default:
                break;
        }
        return true;
    }
}
